Answer:
5.5%
Step-by-step explanation:
This is an Annuity Due question. In an annuity due, recurring payments occur at the beginning of the yearIt is asking for the RATE. Using a financial calculator(on BEG mode), input the following;
Duration; N = 25
Recurring payment; PMT = 23.6
Present value ; PV = -334
One-time future cashflow; FV = 0
Then compute the interest rate; CPT I/Y = 5.499%
Therefore, the lottery commission is using about 5.5% interest rate.
